Audi has gone and gotten fancy with its green car concept on display at the ongoing Paris Motor Show. Dubbed the crosslane coupe, what’s mostly interesting about this vehicle beyond its sporty look is its dual mode hybrid design.
The crosslane coupe, according to Audi, is a plug-in hybrid design study compromising a 1.5-liter three-cylinder TFSI engine, two electric motors and a single-stage transmission. With system power of 130 kW (177 hp), it is said to be able to do zero to 100 km/h (62.14 mph) in 8.6 seconds and has a top speed of 182 km/h (113.09 mph). Average fuel consumption is 1.1 liters per 100 km (213.81 US mpg) and it emits 26 grams per km (41.84 grams per mile) of CO2.
The vehicle is also capable of operating in electric only mode, hitting 62 MPH in 9.8 seconds and having a driving range of around 86 km (53.44 miles).
With regards to what Audi dubs the dual mode hybrid design, the crosslane coupe is capable of operating in different modes. From 0 up to 55 km/h (34.18 mph), drive power is supplied by the second electric motor (85 kW (116 hp) and 250 Nm (184.39 lb-ft) of torque), which draws the energy it needs primarily from the battery. In serial mode, the combustion engine and the first electric motor (50 kW (68 hp) and 210 Nm (154.89 lb-ft) of torque), which acts primarily as a starter and an alternator, produce electrical energy to support, relieve or substitute the battery should it be discharged.
The electric mode is possible up to 130 km/h (80.78 mph), according to Audi. Starting at about 55 km/h (34.18 mph) the drive system allows the TFSI engine together with the alternator to couple to the drivetrain for what is said to be better efficiency and performance. Above 130 km/h (80.78 mph), the three-cylinder engine becomes the main drive source but the first electric motor can support it if required.
Moving beyond the mechanics of the crosslane, Audi has developed what it calls a Multimaterial Space Frame for the vehicle’s structure. It consists of three materials – aluminum, carbon fiber-reinforced polymer (CFRP), and glass fiber-reinforced polymer (GFRP). These all perform various functions, whether it is improved crash safety, lower body costs or improved energy usage.
As with other concept designs, there are various bells and whistles thrown in for that little extra wow factor. In the case of the crosslane coupe, these include a moveable trunk that shifts forward electrically for more usable storage space, virtual displays in the instrument cluster that can be toggled between two different levels, a powermeter that visualizes the drive system’s operating statuses and tight social media integration via Facebook or Twitter that allows drivers to share photos and videos recorded on the road.
